用户的详细注册和判断

有三个文件：
第一是:zcyh.php（注册用户名）

 1<div align="center">
 2<table border="0" width="89%">
 3<tr>
 4<td><font color="#ff0000">当前位置：<a href="index.php">主页</a>&gt;&gt;注册页面</font></td>
 5</tr>
 6</table><br/>
 7<table border="0" height="27" width="82%">
 8<tr>
 9<td height="14"><b><font color="#660099"><img height="22" src="images/dyb.gif" width="68"/>   
10请设定用户名：（<font color="#FF0000">3-15位</font>）</font></b></td>
11</tr>
12</table>
13<form action="register.php" method="post" name="form1">
14<table border="0" height="154" width="80%">
15<tr>
16<td width="42%">

19<td width="58%">

21</td></tr></table></form></div>

1<tr>
2<td colspan="2" height="27">
3<div align="left"><font size="2"><font color="#FF0000">注意：</font><font color="#0000FF">用户名只能由英文字母（a-z），数字（0-9）和下划线（'_'、'-'、'.'   
4）构成，不能有空格，且必须以英文字母为开头。 </font></font> </div>
5</td>
6</tr>

1<tr>

5</tr>

1<tr>

5</tr>

5</font></div>
6</td>
7</tr>

1<tr>
2<td colspan="2" height="19">
3<div align="center">
4<input border="0" height="22" name="name2" src="images/xyb.gif" type="image" width="68"/>
5<input name="name3" type="hidden" value="&lt;?echo$name?"/>&gt;   
6<a href="zcyh.php"><img border="0" height="22" src="images/cancel.gif" width="68"/></a></div>
7</td>
8</tr>

1<br/>

1<br/>

第二个是：register.php(判断注册用户名是否正确和是否重复，然后输出注册的详细表单)

 1<div align="center">
 2<table border="0" width="89%">
 3<tr>
 4<td><font color="#ff0000">当前位置：<a href="index.php">主页</a>&gt;&gt;<a href="zcyh.php">注册页面</a>&gt;&gt;详细资料</font></td>

第三个是：check.php(判断注册资料是否正确，然后插入数据库，重新登录)
